Drill collars

The drill collars are made of modified AISI 4145H chromium molybdenum alloy steel. These drill collar bars are full-length heat treated and water quenched to obtain ASTM A-370 mechanical properties. Full mechanical and chemical mill test certifications are supplied with all drill collars. These mill test certifications guarantee a hardness range of 285 to 341 BHN and an impact value of 40 ft.-lbs. at room temperature one inch below the surface.

To ensure close tolerance bores, all drill collar bars are trepanned then drifted to API specifications. Bar surface finish is “as rolled” which is original mill finish.

CONNECTIONS: All connections are precision-machined to API specifications. API relief groove pin and bore back box stress relief are available on request. Thread roots are cold-worked to offer a greater resistance to fatigue. All connections are phosphated to minimize galling during makeup and applied with thread storage compound. Thread protectors are installed to ensure adequate joint protection during shipment.

Spiral drill collars

The spiral cut is added to a drill collar to prevent the likelihood of differential wall-sticking by reducing wall contact between the drill collar and the wall of the hole. The box end of the spiral collar is left uncut from 79 inches from box shoulder and the pin end is left uncut 30 inches from the pin shoulder.

When ordering or requesting quotations on drill collars, please specify:

Out side diameter, bore and length

Size and type of connection: each end of collar and special joint features Slick or Spiral

Other special features: slip and elevator recesses and/or hard band type.

Heavy weight drill pipe

Improve drill string perform-ance with the recommended use of Heavy weight drill pipe.

Heavy Weight Drill Pipe is the industry standard for an intermediate weight drill stem member and is available in standard, spiraled and non-magnetic designs making it useful in a number of applications. It has drill pipe dimensions for easier handling. Heavy weight drill pipe utilizes a unique centre upset or wear pad to increase tube life, reduce hole drag and differential sticking problems.

Spiral heavy weight drill pipe

QUALITY CONTROL

Each piece of Integral Spiral Heavy Weight Drill Pipe is 100% dimensionally inspected and the material is full length ultrasonically inspected. All connections are 100% inspected to conform to latest API standards. Full material certifications are provided with each piece of Integral Spiral Heavy Weight Drill Pipe.

HARDBANDING

To optimize wear resistance, hardbanding is standard on tool joint connections and central upset. This heavy-duty hardmetal application is a closely controlled welding process applied with an automatic hardbanding machine. Hardbanding is applied 4" on the box tool joint, 4" on the pin tool joint, 1" on 18 tapered shoulder of box tool joint and two 3" band on center upset. Tungsten carbide, Arnco 100XT, Arnco 200XT, Arnco 300XT, Smooth X, ARMACOR-M and TCS TITANIUM Hardbandings are available.

CONNECTION FEATURES

API stress relief groove on pins and boreback relief feature on boxes are standard on the 4½ " and 5" Spiral Heavy Weight Drill Pipes. All connections are kemplated, coated with lubricant and provided with thread protectors. Thread roots are cold rolled on all sizes.
